I don't think your a racist, but I do think your a wimp for feeling you have to preface your argument with "hey everybody I have a black friend."

You sound like you're apologizing for your existence. Just because some dumbass author with an agenda tries to paint everyone who doesn't agree with him with the "R" word, doesn't mean you have to play along.

Bravo! By defending yourself, you admit that they even have an argument to begin with.
